According to one embodiment, a switch circuit switches a resonance frequency band of an antenna in a display unit between first and second resonance frequency bands. The second resonance frequency band is overlapped with a part of the first resonance frequency band and is higher than the first resonance frequency band. A wireless communication module wirelessly transmits and receives signals using a transmission frequency band and a reception frequency band which are included in the first resonance frequency band. A screen image orientation control module changes an orientation of a screen image displayed on the display unit. A resonance frequency shift module shifts the resonance frequency band of the antenna from the first resonance frequency band to the second frequency band by controlling the switch circuit when the orientation of the screen image is an orientation in which the antenna is positioned on a downward side of the screen image.
